Constructor Detail

LazyMetaPropertyMap

public LazyMetaPropertyMap(java.lang.Object o)
Constructs the map
Parameters:
o - The object to inspect

 
Method Detail

clear

public void clear()
throws:
UnsupportedOperationException

containsKey

public boolean containsKey(java.lang.Object propertyName)
{@inheritDoc}
See Also:
java.util.Map#containsKey(java.lang.Object)

containsValue

public boolean containsValue(java.lang.Object o)
Checks whether the specified value is contained within the Map. Note that because this implementation lazily initialises property values the behaviour may not be consistent with the actual values of the contained object unless they have already been initialised by calling get(Object)
See Also:
java.util.Map#containsValue(Object)

entrySet

public java.util.Set entrySet()

equals

@Override
public boolean equals(java.lang.Object o)

get

public java.lang.Object get(java.lang.Object propertyName)
Obtains the value of an object's properties on demand using Groovy's MOP.
Parameters:
propertyName - The name of the property
Returns:
The property value or null

getInstance

public java.lang.Object getInstance()
Returns the wrapped instance.
Returns:
The wrapped instance

hashCode

@Override
public int hashCode()

isEmpty

public boolean isEmpty()
{@inheritDoc}
See Also:
java.util.Map#isEmpty()

keySet

public java.util.Set keySet()

put

public java.lang.Object put(java.lang.Object propertyName, java.lang.Object propertyValue)

putAll

public void putAll(java.util.Map map)

remove

public java.lang.Object remove(java.lang.Object o)
throws:
UnsupportedOperationException

size

public int size()
{@inheritDoc}
See Also:
java.util.Map#size()
