Constructor Detail

JMethodSignature

public JMethodSignature(String name)

Creates a new method with the given name and "void" return type.

Parameters:

name - The method name. Must not be null.

JMethodSignature

public JMethodSignature(String name,
                        JType returnType)

Creates a new method with the given name and return type.

Parameters:

name - The method name. Must not be null.

returnType - The return type of the method. Must not be null.

Method Detail

addException

public void addException(JClass exp)

Adds the given Exception to this JMethodSignature's throws clause.

Parameters:

exp - The JClass representing the Exception.

addParameter

public void addParameter(JParameter parameter)

Adds the given parameter to this JMethodSignature's list of parameters.

Parameters:

parameter - The parameter to add to the this JMethodSignature's list of parameters.

getExceptions

public JClass[] getExceptions()

Returns the exceptions that this JMethodSignature lists in its throws clause.

Returns:

The exceptions that this JMethodSignature lists in its throws clause.

getJDocComment

public JDocComment getJDocComment()

Returns the JavaDoc comment describing this JMethodSignature.

Returns:

The JavaDoc comment describing this JMethodSignature.

getModifiers

public JModifiers getModifiers()

Returns the modifiers for this JMethodSignature.

Returns:

The modifiers for this JMethodSignature.

getName

public String getName()

Returns the name of the method.

Returns:

The name of the method.

getParameter

public JParameter getParameter(int index)

Returns the JParameter at the given index.

Parameters:

index - The index of the JParameter to return.

Returns:

The JParameter at the given index.

getParameters

public JParameter[] getParameters()

Returns the set of JParameters in this JMethodSignature.
Note: the array is a copy, the parameters in the array are the actual references.

Returns:

The set of JParameters in this JMethodSignature.

getReturnType

public JType getReturnType()

Returns the JType that represents the return type for the method signature.

Returns:

The JType that represents the return type for the method signature.

setName

public void setName(String name)

Sets the name of the method.

Parameters:

name - The name of the method.

setComment

public void setComment(String comment)

Sets the JavaDoc comment describing this JMethodSignature.

Parameters:

comment - The JavaDoc comment for this member.

setModifiers

public void setModifiers(JModifiers modifiers)

Sets the JModifiers for this method signature.

Parameters:

modifiers - The JModifiers for this method signature.

getParameterClassNames

protected String[] getParameterClassNames()

Returns an array containing the names of the classes of the parameters in this JMethodSignature. For Arrays, the class name of the object type stored in the Array is what is returned. Parameters that are primitive types (and Arrays of primitive types) are not represented in the array of names returned.

Returns:

An array containing the names of the classes of the parameters in this JMethodSignature.

print

public void print(JSourceWriter jsw)

Prints the method signature. A semi-colon (end-of-statement terminator ';') will not be printed.

Parameters:

jsw - The JSourceWriter to print to.

print

public void print(JSourceWriter jsw,
                  boolean printJavaDoc)

Prints the method signature. A semi-colon (end-of-statement terminator ';') will not be printed.

Parameters:

jsw - The JSourceWriter to print to.

printJavaDoc - If true, print the JDocComment associated with this method signature before we print the method signature.

toString

public String toString()

Overrides:

toString in class Object
