Detailed Description

A wrapper type for long proxies. This type wraps the Java long type in a proxy type that uses the JNI jlong type to repesent the Java type. Conversion operators allow convenient usage while the get/set methods take an optional xmog_localenv argument for better performance (by saving at least a threadlocal memory access).

Constructor & Destructor Documentation

xmog_long::xmog_long (  xmog_java_array *  _ref, jint  _index )

Creates an instance that acts as a proxy for an element of a long array. Parameters: _ref  a pointer to an array proxy element. _index  the index of the element.

xmog_long::xmog_long (  xmog_java_ref *  _clazz_ref_array, xmog_java_dynamic *  _dynamic, xmog_flags  _flags = 0 )

Creates an instance that acts as a proxy for an indirect element of long type. Parameters: _clazz_ref_array  a pointer to the owner of the primitive value. _dynamic  the algorithm to access the value. _flags  additional processing arguments.

Member Function Documentation

jlong xmog_long::get (  xmog_localenv *  env = NULL, bool  readThrough = false )  const

Returns the value of a long proxy instance. This method takes two optional arguments that can be used to improve overall performance or force a read from the Java side even if a cached value is available. Parameters: env  a local environment pointer. May be NULL. readThrough  true if the value should be read from the Java side unconditionally, false if a cached value should be used if available. This flag is ignored if the instance does not use caching or if it does not yet have a cached value.

xmog_long& xmog_long::operator &= (  jlong   )

The bitwise-AND assignment operator. This operator allows the use of proxy instances of this type in any place where the compiler expects a primitive jlong lhs-value. You can achieve better performance by using the set(jbyte,xmog_localenv*,bool) method with the proper arguments.

jlong xmog_long::operator * (   )  const

The dereference operator converts to the jlong type. This operator is declared to support array iterators.

xmog_long& xmog_long::operator *= (  jlong   )

The multiplicative assignment operator. This operator allows the use of proxy instances of this type in any place where the compiler expects a primitive jlong lhs-value. You can achieve better performance by using the set(jbyte,xmog_localenv*,bool) method with the proper arguments.

xmog_long::operator jlong (   )  const

A conversion operator to the long type. This operator allows the use of proxy instances of this type in any place where the compiler expects a primitive jlong rhs-value. You can achieve better performance by using the get(xmog_localenv*,bool) method with the proper arguments.

xmog_long& xmog_long::operator%= (  jlong   )

The modulo assignment operator. This operator allows the use of proxy instances of this type in any place where the compiler expects a primitive jlong lhs-value. You can achieve better performance by using the set(jbyte,xmog_localenv*,bool) method with the proper arguments.

xmog_long& xmog_long::operator+= (  jlong   )

The additive assignment operator. This operator allows the use of proxy instances of this type in any place where the compiler expects a primitive jlong lhs-value. You can achieve better performance by using the set(jbyte,xmog_localenv*,bool) method with the proper arguments.

xmog_long& xmog_long::operator-= (  jlong   )

The subtractive assignment operator. This operator allows the use of proxy instances of this type in any place where the compiler expects a primitive jlong lhs-value. You can achieve better performance by using the set(jbyte,xmog_localenv*,bool) method with the proper arguments.

xmog_long& xmog_long::operator/= (  jlong   )

The divisive assignment operator. This operator allows the use of proxy instances of this type in any place where the compiler expects a primitive jlong lhs-value. You can achieve better performance by using the set(jbyte,xmog_localenv*,bool) method with the proper arguments.

xmog_long& xmog_long::operator<<= (  int   )

The bitwise-shift LEFT assignment operator. This operator allows the use of proxy instances of this type in any place where the compiler expects a primitive jlong lhs-value. You can achieve better performance by using the set(jbyte,xmog_localenv*,bool) method with the proper arguments.

xmog_long& xmog_long::operator= (  jlong   )

An assignment operator from the long type. This operator allows the use of proxy instances of this type in any place where the compiler expects a primitive jlong lhs-value. You can achieve better performance by using the set(jlong,xmog_localenv*,bool) method with the proper arguments.

xmog_long& xmog_long::operator>>= (  int   )

The bitwise-shift RIGHT assignment operator. This operator allows the use of proxy instances of this type in any place where the compiler expects a primitive jlong lhs-value. You can achieve better performance by using the set(jbyte,xmog_localenv*,bool) method with the proper arguments.

xmog_long& xmog_long::operator^= (  jlong   )

The bitwise-XOR assignment operator. This operator allows the use of proxy instances of this type in any place where the compiler expects a primitive jlong lhs-value. You can achieve better performance by using the set(jbyte,xmog_localenv*,bool) method with the proper arguments.

xmog_long& xmog_long::operator|= (  jlong   )

The bitwise-OR assignment operator. This operator allows the use of proxy instances of this type in any place where the compiler expects a primitive jlong lhs-value. You can achieve better performance by using the set(jbyte,xmog_localenv*,bool) method with the proper arguments.

void xmog_long::set (  jlong  l, xmog_localenv *  env = NULL, bool  writeThrough = false )

Sets the value of a long proxy. This method takes two optional arguments that can be used to improve overall performance or force a write to the Java side even if the CACHE_LAZY_WRITE policy is in effect for this instance. Parameters: l  the new value. env  a local environment pointer. May be NULL. writeThrough  true if the value should be written to the Java side unconditionally, false if only the cached value should be updated. This flag is ignored if the instance does not use caching.
