Method Details

values

public static Operator[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

an array containing the constants of this enum class, in the order they are declared

valueOf

public static Operator valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum class has no constant with the specified name

NullPointerException - if the argument is null

writeTo

public void writeTo(DataOutput output)
             throws IOException

Write the serialized version of this Operator to the specified output.

Parameters:

output - the output to write to

Throws:

IOException - if an I/O problem occurs while writing to the specified output

getValue

public int getValue()

readFrom

public static Operator readFrom(DataInput input)
                         throws IOException

Deserializes a Operator instance from the specified input.

Parameters:

input - the input to read from

Returns:

the Operator instance deserialized

Throws:

IOException - if a problem occurs while deserializing the Type instance.

isSatisfiedBy

public abstract boolean isSatisfiedBy(AbstractType<?> type,
 ByteBuffer leftOperand,
 ByteBuffer rightOperand)

Whether 2 values satisfy this operator (given the type they should be compared with).

serializedSize

public int serializedSize()

isSlice

public boolean isSlice()

Checks if this operator is a slice operator.

Returns:

true if this operator is a slice operator, false otherwise.

toString

public String toString()

Overrides:

toString in class Enum<Operator>

isIN

public boolean isIN()

Checks if this operator is an IN operator.

Returns:

true if this operator is an IN operator, false otherwise.

isContains

public boolean isContains()

Checks if this operator is CONTAINS operator.

Returns:

true if this operator is a CONTAINS operator, false otherwise.

isContainsKey

public boolean isContainsKey()

Checks if this operator is CONTAINS KEY operator.

Returns:

true if this operator is a CONTAINS operator, false otherwise.
