Method Detail

equalTo back to summary

equalTo	back to summary
private boolean equalTo(byte[] buf, int offset, int size) Check whether the internal buffer contains the same data as another byte buffer. Parameters buf:byte[] a byte array offset:int start position in the byte array size:int how many bytes to read from the byte array Returns:boolean `true` if the internal buffer contains the same data as the specified byte array

private boolean equalTo(byte[] buf, int offset, int size)

Check whether the internal buffer contains the same data as another byte buffer.

Parameters

buf:byte[]: a byte array
offset:int: start position in the byte array
size:int: how many bytes to read from the byte array

Returns:boolean

true if the internal buffer contains the same data as the specified byte array

getBytes back to summary

getBytes	back to summary
public byte[] getBytes() Return the internal byte array. The returned array should not be modified, as it is used internally in `DRDAString`. The value of the array might be modified by subsequent calls to `DRDAString.setBytes()`. Returns:byte[] internal buffer

public byte[] getBytes()

Return the internal byte array. The returned array should not be modified, as it is used internally in DRDAString. The value of the array might be modified by subsequent calls to DRDAString.setBytes().

Returns:byte[]: internal buffer

length	back to summary
public int length() Return the length in bytes of the internal string representation. Returns:int length of internal representation

length

back to summary

public int length()

Return the length in bytes of the internal string representation.

Returns:int: length of internal representation

setBytes	back to summary
public void setBytes(byte[] src, int offset, int size) Modify the internal byte buffer. If the new data is equal to the old data, the cached values are not cleared. Parameters src:byte[] the new bytes offset:int start offset size:int number of bytes to use

setBytes

back to summary

public void setBytes(byte[] src, int offset, int size)

Modify the internal byte buffer. If the new data is equal to the old data, the cached values are not cleared.

Parameters

src:byte[]: the new bytes
offset:int: start offset
size:int: number of bytes to use

toString back to summary

toString	back to summary
public String toString() Overrides java.lang.Object.toString. Convert the internal byte array to a string. The string value is cached. Returns:String a `String` value

public String toString()

Overrides java.lang.Object.toString.

Convert the internal byte array to a string. The string value is cached.

Returns:String: a String value

wasModified back to summary

wasModified	back to summary
public boolean wasModified() Check whether the contents of the `DRDAString` were modified in the previous call to `setBytes()`. Returns:boolean `true` if the contents were modified

public boolean wasModified()

Check whether the contents of the DRDAString were modified in the previous call to setBytes().

Returns:boolean: true if the contents were modified
