Method Detail

getType

public int getType()

return the type of this CosObject

Specified by:

getType in class CosObject

Returns:

one of the t_Mumble static final int values defined above

byteArrayValue

public byte[] byteArrayValue()
                      throws PDFSecurityException

Obtains the string data. The first time the method is called, the string data is decrypted, if necessary, and the desired portion of the original data buffer is extracted.

Returns:

Byte array containing the string data.

Throws:

PDFSecurityException

stringValue

public ASString stringValue()
                     throws PDFSecurityException

Description copied from class: CosObject

Returns string value if it's type of CosString else throws exception.

Overrides:

stringValue in class CosObject

Throws:

PDFSecurityException

hexStringValue

public ASHexString hexStringValue()
                           throws PDFSecurityException

Description copied from class: CosObject

Returns hex string value if it's type of CosString else throws exception.

Overrides:

hexStringValue in class CosObject

Throws:

PDFSecurityException

asString

public java.lang.String asString()
                          throws PDFSecurityException

Returns String value.

Throws:

PDFSecurityException

getValue

public java.lang.Object getValue()
                          throws PDFSecurityException

Specified by:

getValue in class CosObject

Returns:

Object value of CosObject

Throws:

PDFSecurityException

textValue

public java.lang.String textValue()
                           throws PDFSecurityException

Creates an instance of a String object "wrapping" the specified CosString. This method is called by the Factory class. A Class implementing the Constructible interface must implement this method.

Overrides:

textValue in class CosObject

Returns:

Newly created String object or null if data is null.

Throws:

PDFSecurityException

setDataInternal

public void setDataInternal(byte[] newData,
                            boolean markDirty)
                     throws PDFCosParseException,
                            PDFIOException,
                            PDFSecurityException

Only for internal engineering use. This api can change without notice. Hack for DigSig. Overwrite string contents with passed byte array.

Throws:

PDFCosParseException

PDFIOException

PDFSecurityException

toString

public java.lang.String toString()

Overrides:

toString in class CosObject

asDate

public ASDate asDate()
              throws PDFCosParseException,
                     PDFSecurityException

Returns this string as ASDate if it's in proper date format else throws exception.

Throws:

PDFCosParseException

getWriteHex

public boolean getWriteHex()

Returns true if this string is written in hex format.

isOddBall

public boolean isOddBall()

Returns true if this is hex string and ended on odd nibble.

setToEncrypt

public void setToEncrypt(boolean encrypted)

Sets true if string is to be encrypted.

getToEncrypt

public boolean getToEncrypt()

Returns true if string is to be encrypted.

setIsEncrypted

public void setIsEncrypted(boolean encrypted)

Sets the flag which tells whether this string is already encrypted or not.

getIsEncrypted

public boolean getIsEncrypted()

Tells whether this string is already encrypted or not.

equals

public boolean equals(ASString string)

equals

public boolean equals(CosString string)

equals

public boolean equals(CosObject value)

Specified by:

equals in class CosObject

Parameters:

value -

Returns:

boolean

equals

public boolean equals(byte[] b)
