Field Details

DISABLE_EXTRACT_PROP

public static final String DISABLE_EXTRACT_PROP

Java system property name that can be set to disable automatic extraction of the LMDB system library from the LmdbJava JAR. This may be desirable if an operating system-provided LMDB system library is preferred (eg operating system package management, vendor support, special compiler flags, security auditing, profile guided optimization builds, faster startup time by avoiding the library copy etc).

• Constant Field Values

LMDB_EXTRACT_DIR_PROP

public static final String LMDB_EXTRACT_DIR_PROP

Java system property name that can be set to the path of an existing directory into which the LMDB system library will be extracted from the LmdbJava JAR. If unspecified the LMDB system library is extracted to the java.io.tmpdir. Ignored if the LMDB system library is not being extracted from the LmdbJava JAR (as would be the case if other system properties defined in Library have been set).

See Also:

• Constant Field Values

LMDB_NATIVE_LIB_PROP

public static final String LMDB_NATIVE_LIB_PROP

Java system property name that can be set to provide a custom path to a external LMDB system library. If set, the system property DISABLE_EXTRACT_PROP will be overridden.

• Constant Field Values

SHOULD_EXTRACT

public static final boolean SHOULD_EXTRACT

Indicates whether automatic extraction of the LMDB system library is permitted.
