Method Details

checkpoint

public ImmutableMapImpl checkpoint()

Specified by:

checkpoint in interface ImmutableMap

Returns:

a new instance of ImmutableMap, which inherits all values from this ImmutableMap Any call of ImmutableMap.putValue(String, Object) is remembered in local Map of parameters. At the end of process the ImmutableMap.getModifiedValues() can be used to return all the parameters which were changed after local ImmutableMap was created

hasValue

public boolean hasValue(String parameterName)

Specified by:

hasValue in interface ImmutableMap

Parameters:

parameterName - to be checked parameter name

Returns:

true if there is defined some value for the parameter. null can be a value too

getValue

public Object getValue(String parameterName)

Specified by:

getValue in interface ImmutableMap

Parameters:

parameterName - the name of the parameter

Returns:

a value of the parameter under the name `parameterNamer

putValue

public ImmutableMap putValue(String parameterName,
 Object value)

Specified by:

putValue in interface ImmutableMap

Parameters:

parameterName - to be set parameter name

value - the new value

Returns:

copies this ImmutableMap, sets the new value there and returns that copy

toString

public String toString()

Overrides:

toString in class Object

asMap

public Map<String,Object> asMap()

Specified by:

asMap in interface ImmutableMap

Returns:

underlying unmodifiable Map<String, Object>

getModifiedValues

public Map<String,Object> getModifiedValues()

Specified by:

getModifiedValues in interface ImmutableMap

Returns:

the modified parameters since last call to ImmutableMap.checkpoint()

equals

public boolean equals(Object obj)

Overrides:

equals in class Object
