Constructor Detail

PredicateConfig

public PredicateConfig()

Creates a PredicateConfig without className/implementation.

PredicateConfig

public PredicateConfig(java.lang.String className)

Creates a PredicateConfig with the given className.

Parameters:

className - the name of the Predicate class

Throws:

java.lang.IllegalArgumentException - if className is null or an empty String

PredicateConfig

public PredicateConfig(PredicateConfig config)

PredicateConfig

public PredicateConfig(Predicate implementation)

Creates a PredicateConfig with the given implementation.

Parameters:

implementation - the implementation to use as Predicate

Throws:

java.lang.IllegalArgumentException - if the implementation is null

Method Detail

getClassName

public java.lang.String getClassName()

Returns the name of the class of the Predicate. If no class is specified, null is returned.

Returns:

the class name of the Predicate

See Also:

setClassName(String)

setClassName

public PredicateConfig setClassName(java.lang.String className)

Sets the class name of the Predicate.

If a implementation or sql was set, it will be removed.

Parameters:

className - the name of the class of the Predicate

Returns:

the updated PredicateConfig

Throws:

java.lang.IllegalArgumentException - if className is null or an empty String

See Also:

setImplementation(Predicate), getClassName()

getImplementation

public Predicate getImplementation()

Returns the Predicate implementation. If none has been specified, null is returned.

Returns:

the Predicate implementation

See Also:

setImplementation(Predicate)

setImplementation

public PredicateConfig setImplementation(Predicate implementation)

Sets the Predicate implementation.

If a className or sql was set, it will be removed.

Parameters:

implementation - the Predicate implementation

Returns:

the updated PredicateConfig

Throws:

java.lang.IllegalArgumentException - the implementation is null

See Also:

setClassName(String), getImplementation()

getSql

public java.lang.String getSql()

Returns sql string for this config.

Returns:

sql string for this config

setSql

public PredicateConfig setSql(java.lang.String sql)

Sets sql string for this config.

If a className or implementation was set, it will be removed.

Parameters:

sql - sql string for this config

Returns:

this configuration

equals

public boolean equals(java.lang.Object o)

Overrides:

equals in class java.lang.Object

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

getFactoryId

public int getFactoryId()

Description copied from interface: IdentifiedDataSerializable

Returns DataSerializableFactory factory ID for this class.

Specified by:

getFactoryId in interface IdentifiedDataSerializable

Returns:

factory ID

getClassId

public int getClassId()

Description copied from interface: IdentifiedDataSerializable

Returns type identifier for this class. It should be unique per DataSerializableFactory.

Specified by:

getClassId in interface IdentifiedDataSerializable

Returns:

type ID

writeData

public void writeData(ObjectDataOutput out)
               throws java.io.IOException

Description copied from interface: DataSerializable

Writes object fields to output stream

Specified by:

writeData in interface DataSerializable

Parameters:

out - output

Throws:

java.io.IOException - if an I/O error occurs. In particular, an IOException may be thrown if the output stream has been closed.

readData

public void readData(ObjectDataInput in)
              throws java.io.IOException

Description copied from interface: DataSerializable

Reads fields from the input stream

Specified by:

readData in interface DataSerializable

Parameters:

in - input

Throws:

java.io.IOException - if an I/O error occurs. In particular, an IOException may be thrown if the input stream has been closed.
