Member Enumeration Documentation

Mode

template<typename T, typename U>

enum jau::jni::JNICriticalArray::Mode : jint

Enumerator
UPDATE_AND_RELEASE	Like default 0: If 'isCopy': Update the java array data with the copy and free the copy.
UPDATE_NO_RELEASE	Like JNI_COMMIT: If 'isCopy': Update the java array data with the copy, but do not free the copy.
NO_UPDATE_AND_RELEASE	Like default JNI_ABORT: If 'isCopy': Do not update the java array data with the copy, but free the copy.

get()

template<typename T, typename U>

T * jau::jni::JNICriticalArray< T, U >::get ( U jarray_val, Mode mode_val = UPDATE_AND_RELEASE )

inline

Acquired the primitive array.

Definition at line 192 of file jni_mem.hpp.

getIsCopy()

template<typename T, typename U>

bool jau::jni::JNICriticalArray< T, U >::getIsCopy ( ) const

inline

Returns true if the primitive array had been acquired and the JVM utilizes a copy of the underlying java array.
