class jau::jni::JNICriticalArray< T, U >

Definition at line 142 of file jni_mem.hpp.

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.

Member Function Documentation

◆ operator=() [1/2]

template<typename T , typename U >
JNICriticalArray & jau::jni::JNICriticalArray< T, U >::operator= ( const JNICriticalArray< T, U > &  o)
delete

◆ operator=() [2/2]

template<typename T , typename U >
JNICriticalArray & jau::jni::JNICriticalArray< T, U >::operator= ( JNICriticalArray< T, U > &&  o)
delete

◆ release()

template<typename T , typename U >
void jau::jni::JNICriticalArray< T, U >::release ( )
inline

Here is the caller graph for this function:

◆ get()

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

Acquired the primitive array.

Definition at line 193 of file jni_mem.hpp.

Here is the caller graph for this function:

◆ 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.
