Detailed Description

A wrapper type for double proxies. This type wraps the Java double type in a proxy type that uses the JNI jdouble 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_double::xmog_double (  xmog_java_array *  _ref, jint  _index )

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

xmog_double::xmog_double (  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 double 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

jdouble xmog_double::get (  xmog_localenv *  env = NULL, bool  readThrough = false )  const

Returns the value of a double 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.

jdouble xmog_double::operator * (   )  const

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

xmog_double& xmog_double::operator *= (  jdouble   )

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

xmog_double::operator jdouble (   )  const

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

xmog_double& xmog_double::operator+= (  jdouble   )

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

xmog_double& xmog_double::operator-= (  jdouble   )

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

xmog_double& xmog_double::operator/= (  jdouble   )

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

xmog_double& xmog_double::operator= (  jdouble   )

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

void xmog_double::set (  jdouble  d, xmog_localenv *  env = NULL, bool  writeThrough = false )

Sets the value of a double 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: d  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.
