Constructor Detail

SystemNativeLibraryProperties

public SystemNativeLibraryProperties(java.lang.String libraryName,
                                     java.lang.String propertyPrefix)

Method Detail

getLibraryPath

public java.lang.String getLibraryPath()

Specified by:

getLibraryPath in interface NativeLibraryProperties

Returns:

Explicit filesystem path for the library. If this is set, this is loaded directly and no resource extraction and/or system name detection is performed. If this returns null, library directory is checked next.

getLibraryDirectory

public java.lang.String getLibraryDirectory()

Specified by:

getLibraryDirectory in interface NativeLibraryProperties

Returns:

Explicit directory containing the native library. The specified directory must contain the system name directories, thus the library to be loaded is actually located at directory/{systemName}/{libPrefix}{libName}{libSuffix}. If this returns null, then NativeLibraryBinaryProvider.getLibraryStream(SystemType, String) is called to obtain the stream to the library file, which is then written to disk for loading.

getExtractionPath

public java.lang.String getExtractionPath()

Specified by:

getExtractionPath in interface NativeLibraryProperties

Returns:

Base directory where to write the library if it is obtained through NativeLibraryBinaryProvider.getLibraryStream(SystemType, String). The library file itself will actually be written to a subdirectory with a randomly generated name. The specified directory does not have to exist, but in that case the current process must have privileges to create it. If this returns null, then {tmpDir}/lava-jni-natives is used.

getSystemName

public java.lang.String getSystemName()

Specified by:

getSystemName in interface NativeLibraryProperties

Returns:

System name. If this is set, no operating system or architecture detection is performed.

getArchitectureName

public java.lang.String getArchitectureName()

Specified by:

getArchitectureName in interface NativeLibraryProperties

Returns:

Architecture name to use. If this is set, operating system detection is still performed.

getLibraryFileNamePrefix

public java.lang.String getLibraryFileNamePrefix()

Specified by:

getLibraryFileNamePrefix in interface NativeLibraryProperties

Returns:

Library file name prefix to use. Only used when NativeLibraryProperties.getSystemName() is provided.

getLibraryFileNameSuffix

public java.lang.String getLibraryFileNameSuffix()

Specified by:

getLibraryFileNameSuffix in interface NativeLibraryProperties

Returns:

Library file name suffix to use. Only used when NativeLibraryProperties.getSystemName() is provided.
