DataField

All Known Implementing Classes:

AbstractDataIntField, CompactCharField, CompactIntField, DateField, DecimalField, LongField, PlainIntField, SequenceField, ShortStringField, TimeField, TimeMillisField, TimeSecondsField, VoidIntField, WideDecimalField

public interface DataIntField
extends DataField

The DataIntField defines identity and access API for Int-fields.

Method Summary

Modifier and Type	Method and Description
boolean	equals(int value1, int value2) Compares two specified field values for equality.
int	parseString(String value) Parses string representation of specified field value.
int	readInt(com.devexperts.io.BufferedInput in) Reads field value from specified buffered input and returns it to the caller.
int	readInt(DataInput in) Deprecated. Use readInt(BufferedInput) which is faster.
double	toDouble(int value) Converts raw QD int-value to meaningful double value, or to Double.NaN if inapplicable.
int	toInt(double value) Converts meaningful double value to raw QD int-value, or to 0 if inapplicable.
String	toString(int value) Returns string representation of specified field value.
void	writeInt(com.devexperts.io.BufferedOutput out, int value) Writes specified field value into specified buffered output.
void	writeInt(DataOutput out, int value) Deprecated. Use writeInt(BufferedOutput, int) which is faster.

Method Detail

toString

String toString(int value)

Returns string representation of specified field value. This method is used for debugging purposes.

parseString

int parseString(String value)

Parses string representation of specified field value. This method is used for debugging purposes.

Throws:

IllegalArgumentException - if string cannot be parsed.

toDouble

double toDouble(int value)

Converts raw QD int-value to meaningful double value, or to Double.NaN if inapplicable.

toInt

int toInt(double value)

Converts meaningful double value to raw QD int-value, or to 0 if inapplicable.

equals

boolean equals(int value1,
               int value2)

Compares two specified field values for equality. This method is used for implementation of ticker contract.

writeInt

void writeInt(DataOutput out,
              int value)
       throws IOException

Deprecated. Use writeInt(BufferedOutput, int) which is faster.

Writes specified field value into specified data output.

Throws:

IOException - as specified data output does.

writeInt

void writeInt(com.devexperts.io.BufferedOutput out,
              int value)
       throws IOException

Writes specified field value into specified buffered output.

Throws:

IOException - as specified data output does.

readInt

int readInt(DataInput in)
     throws IOException

Deprecated. Use readInt(BufferedInput) which is faster.

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

Throws:

IOException - as specified data input does.

readInt

int readInt(com.devexperts.io.BufferedInput in)
     throws IOException

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

Throws:

IOException - as specified data input does.
