All Implemented Interfaces:

DataField, DataObjField

public final class StringField
extends AbstractDataObjField

The StringField represents a character sequence field with CESU-8 serialized form. See IOUtil for details. Default representation of the value is String as returned by readObj(java.io.DataInput), but char[], byte[] and arbitrary objects are also supported by writeObj(java.io.DataOutput, java.lang.Object) and toString(Object).

Method Detail

toString

public String toString(Object value)

Description copied from class: AbstractDataObjField

Returns string representation of the specified field value. This method is used for debugging purposes. This implementation returns String.valueOf(value).

Specified by:

toString in interface DataObjField

Overrides:

toString in class AbstractDataObjField

equals

public boolean equals(Object value1,
                      Object value2)

Description copied from class: AbstractDataObjField

Compares two specified field values for equality. This method is used for implementation of ticker contract. This implementation returns value1 == value2 || (value1 != null && value1.equals(value2)).

Specified by:

equals in interface DataObjField

Overrides:

equals in class AbstractDataObjField

writeObj

public final void writeObj(DataOutput out,
                           Object value)
                    throws IOException

Description copied from interface: DataObjField

Writes specified field value into specified data output.

Throws:

IOException - as specified data output does.

writeObj

public final void writeObj(com.devexperts.io.BufferedOutput out,
                           Object value)
                    throws IOException

Description copied from interface: DataObjField

Writes specified field value into specified buffered output.

Throws:

IOException - as specified data output does.

readObj

public final Object readObj(DataInput in)
                     throws IOException

Description copied from interface: DataObjField

Reads field value from specified data input and returns it to the caller.

Throws:

IOException - as specified data input does.

readObj

public final Object readObj(com.devexperts.io.BufferedInput in)
                     throws IOException

Description copied from interface: DataObjField

Reads field value from specified data input and returns it to the caller.

Throws:

IOException - as specified data input does.
