Nested Class Summary

protected static class

ContainerPropertyDescriptor.PluralPattern Encapsulates the conversion from a specific plural type to a specific singular type using a regex expression and a suffix.

Constructor Summary

Method Summary

java.lang.reflect.Method	getAddMethod() Returns the method that should be used when adding values.
java.lang.Class	getElementClass() Uses simple heuristics to attempt to introspect the lists element type.
java.lang.reflect.Method	getInsertMethod() Returns the method that should be used when inserting values.
java.lang.reflect.Method	getRemoveIndexedMethod() Returns the method that should be used when removing values by index.
java.lang.reflect.Method	getRemoveMethod() Returns the method that should be used when removing values.
java.lang.reflect.Method	getReplaceIndexMethod() Returns the method that should be used when replacing values by index.
java.lang.String	getSingularPropertyName() Returns the singular version of the property name that was used during element type detection, or null if detection bypassed this step.
boolean	isArray() Returns true if this property value is actually an array.
static boolean	isContainerType(java.lang.Class type) Returns true if the specified class represents a type that can be handled as a ListPropertyType.
boolean	isList() Returns true if this property value is a list-based implementation.
static boolean	isListType(java.lang.Class type) Returns true if the specified class represents a type that can be handled as a ListPropertyType.
boolean	isMutable() Returns true if the elements can be replaced.
boolean	isResizable() Returns true if the property supports resizing such as with add or remove.
protected boolean	isSingularForm(java.lang.String plural, java.lang.String name) Returns true if the specified name is a possible singular form of the plural property name.
protected void	setupContainerInfo() Attempts to configure the container info values based on some introspection heuristics and guesswork.

Constructor Detail

ContainerPropertyDescriptor

public ContainerPropertyDescriptor(java.lang.Class beanClass,
                                   java.beans.PropertyDescriptor desc)
                            throws java.beans.IntrospectionException

Throws:

java.beans.IntrospectionException

Method Detail

isContainerType

public static boolean isContainerType(java.lang.Class type)

Returns true if the specified class represents a type that can be handled as a ListPropertyType.

isListType

public static boolean isListType(java.lang.Class type)

Returns true if the specified class represents a type that can be handled as a ListPropertyType.

isList

public boolean isList()

Returns true if this property value is a list-based implementation.

isArray

public boolean isArray()

Returns true if this property value is actually an array.

isResizable

public boolean isResizable()

Returns true if the property supports resizing such as with add or remove.

isMutable

public boolean isMutable()

Returns true if the elements can be replaced.

getAddMethod

public java.lang.reflect.Method getAddMethod()

Returns the method that should be used when adding values.

getInsertMethod

public java.lang.reflect.Method getInsertMethod()

Returns the method that should be used when inserting values. This should generally only be valid for list-based types.

getReplaceIndexMethod

public java.lang.reflect.Method getReplaceIndexMethod()

Returns the method that should be used when replacing values by index. This should generally only be valid for list-based types and corresponds to a setFoo( int index, Object value ) or setFoo( Object value, int index ) style method.

getRemoveMethod

public java.lang.reflect.Method getRemoveMethod()

Returns the method that should be used when removing values.

getRemoveIndexedMethod

public java.lang.reflect.Method getRemoveIndexedMethod()

Returns the method that should be used when removing values by index. This should generally only be valid for list-based types.

getSingularPropertyName

public java.lang.String getSingularPropertyName()

Returns the singular version of the property name that was used during element type detection, or null if detection bypassed this step.

getElementClass

public java.lang.Class getElementClass()

Uses simple heuristics to attempt to introspect the lists element type.

isSingularForm

protected boolean isSingularForm(java.lang.String plural,
                                 java.lang.String name)

Returns true if the specified name is a possible singular form of the plural property name.

setupContainerInfo

protected void setupContainerInfo()

Attempts to configure the container info values based on some introspection heuristics and guesswork.
