Method Detail

getSignature

public static java.lang.String getSignature(java.lang.reflect.Method m)

Generates a method signature from Java Reflection method.

Parameters:

m - a java.lang.reflect.Method

Returns:

a signature of given method

isPrimitive

public static boolean isPrimitive(java.lang.String simpleName)

Checks, whether a simple name given represents a primitive type. For example, java.lang.Object returns false, and int returns true.

Parameters:

simpleName - Simple name to check.

Returns:

true, if simpleName represents primitive type.

toMethodSignature

public static java.lang.String toMethodSignature(java.lang.String returnType,
                                                 java.lang.String[] paramTypes)

Creates a method signature from return type and parameter types. All types are in "simple name"-format. (e.g. "java.lang.Object []")

Parameters:

returnType - a return type of a method

paramTypes - method's parameter types

Returns:

a Java VM signature for a method

toSignature

public static java.lang.String toSignature(java.lang.String simpleName)

Convert single simple name to signature.

toSignature

public static java.lang.String[] toSignature(java.lang.String[] simpleNames)

Convert an array of simple names to an array of signatures. For example,
'java.lang.Object' --> 'Ljava/lang/Object;'
'java.lang.Object[]' --> '[Ljava/lang/Object;'
'int' --> 'I'
'int[]' --> '[I'

Returns:

Simple name converted to signature

toSimpleName

public static java.lang.String toSimpleName(java.lang.String signature)

Convert signature to simple name.

toSimpleName

public static java.lang.String[] toSimpleName(java.lang.String[] signatures)

Convert an array of signatures to an array of simple names. For example,
'Ljava/lang/Object;' --> 'java.lang.Object'
'[Ljava/lang/Object;' --> 'java.lang.Object[]'
'I' --> 'int'
'[I' --> 'int[]'

Returns:

signature converted to simple name
