BOOLEAN

public static final BooleanType BOOLEAN

Method Detail

isComparable

public boolean isComparable()

Description copied from interface: Type

True if the type supports equalTo and hash.

Specified by:

isComparable in interface Type

Overrides:

isComparable in class AbstractType

isOrderable

public boolean isOrderable()

Description copied from interface: Type

True if the type supports compareTo.

Specified by:

isOrderable in interface Type

Overrides:

isOrderable in class AbstractType

getObjectValue

public Object getObjectValue(ConnectorSession session,
                    Block block,
                    int position)

Description copied from interface: Type

Gets an object representation of the type value in the block position. This is the value returned to the user via the REST endpoint and therefore must be JSON serializable.

equalTo

public boolean equalTo(Block leftBlock,
              int leftPosition,
              Block rightBlock,
              int rightPosition)

Description copied from interface: Type

Are the values in the specified blocks at the specified positions equal?

Specified by:

equalTo in interface Type

Overrides:

equalTo in class AbstractType

hash

public int hash(Block block,
       int position)

Description copied from interface: Type

Calculates the hash code of the value at the specified position in the specified block.

Specified by:

hash in interface Type

Overrides:

hash in class AbstractType

compareTo

public int compareTo(Block leftBlock,
            int leftPosition,
            Block rightBlock,
            int rightPosition)

Description copied from interface: Type

Compare the values in the specified block at the specified positions equal.

Specified by:

compareTo in interface Type

Overrides:

compareTo in class AbstractType

appendTo

public void appendTo(Block block,
            int position,
            BlockBuilder blockBuilder)

Description copied from interface: Type

Append the value at position in block to blockBuilder.

getBoolean

public boolean getBoolean(Block block,
                 int position)

Description copied from interface: Type

Gets the value at the block position as a boolean.

Specified by:

getBoolean in interface Type

Overrides:

getBoolean in class AbstractType

writeBoolean

public void writeBoolean(BlockBuilder blockBuilder,
                boolean value)

Description copied from interface: Type

Writes the boolean value into the BlockBuilder.

Specified by:

writeBoolean in interface Type

Overrides:

writeBoolean in class AbstractType
