Deprecated.

since 0.11.0; explicit groovy utilities/support will be deleted.

@Deprecated
public class GroovyJavaMethods
extends java.lang.Object

Handy methods available in groovy packaged so they can be consumed from java, and other conversion/conveniences; but see JavaGroovyEquivalents for faster alternatives.

static boolean	safeGroovyIsCase(java.lang.Object switchValue, java.lang.Class caseExpression) Deprecated. Alternative implementation of ScriptBytecodeAdapter.isCase(Object, Object) Stripped down to work only for caseExpression of type java.lang.Class. It behaves the same way only for cases when caseExpression java.lang.Class does not implement isCase method. It goes directly to DefaultGroovyMethods.isCase(Object, Object) method instead of using Groovy dynamic invocation. This saves extra operations and avoids the locks used in Groovy dynamic invocation.
static boolean	truth(java.lang.Object o) Deprecated.
static <any>	truthPredicate() Deprecated.

Deprecated.

Alternative implementation of ScriptBytecodeAdapter.isCase(Object, Object)
Stripped down to work only for caseExpression of type java.lang.Class.
It behaves the same way only for cases when caseExpression java.lang.Class does not implement isCase method.
It goes directly to DefaultGroovyMethods.isCase(Object, Object) method instead of using Groovy dynamic invocation.
This saves extra operations and avoids the locks used in Groovy dynamic invocation. See BROOKLYN-424.
