Method Detail

toSignature

public static String[] toSignature(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'

Parameters:

simpleNames - an Array of simple names

Returns:

An array of signatures in complex form

getSignature

public static String getSignature(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(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.

toSignature

public static String toSignature(String simpleName)

Convert single simple name to signature.

Parameters:

simpleName - Simple name

Returns:

a signature in complex form

toSimpleName

public static String[] toSimpleName(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[]'

Parameters:

signatures - An array of signatures in complex form

Returns:

signature converted to simple name

toSimpleName

public static String toSimpleName(String signature)

Convert signature to simple name.

Parameters:

signature - a signature

Returns:

simple name

toMethodSignature

public static String toMethodSignature(String returnType,
                                       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
