public PdfDictionary(java.util.Map m)

Constructs a dictionary object from a map of PdfName keys and PdfObject values.

Parameters:

m - the map containing the keys and values.

Method Detail

filterContents

protected PdfObject filterContents(PdfObjectFilter f)
                            throws PdfFormatException

Description copied from class: PdfObject

Second stage filtering, called by filter(PdfObjectFilter). This is only called if PdfObjectFilter.preFilter(PdfObject) did not return null.

Overrides:

filterContents in class PdfObject

Returns:

the new filtered object.

Throws:

PdfFormatException

equals

public boolean equals(java.lang.Object obj)

Description copied from class: PdfObject

Compares this instance with another PDF object for equality.

Overrides:

equals in class PdfObject

Parameters:

obj - the object to compare this instance with.

Returns:

true if the PDF objects are equal.

getMap

public java.util.Map getMap()

Returns the map of keys and values contained in this dictionary.

Returns:

the map of keys and values. The returned Map object is unmodifiable.

hashCode

public int hashCode()

Description copied from class: PdfObject

Returns a hash code for this object.

Overrides:

hashCode in class PdfObject

Returns:

the hash code.

wrap

protected static PdfDictionary wrap(java.util.Map m)

A factory for fast construction of this class. The constructed object will be a wrapper around the specified Map. The calling method must ensure that the Map is never externally modified, in order to meet the immutability requirement of PdfObject.

Parameters:

m - the Map to be used to back this dictionary.

Returns:

the constructed object.

writePdf

protected int writePdf(PdfWriter w,
                       boolean spacing)
                throws java.io.IOException

Description copied from class: PdfObject

Writes this object in PDF format.

Specified by:

writePdf in class PdfObject

Parameters:

w - the PdfWriter to write to.

spacing - specifies whether to add white-space before the object. A value of true enables the addition of white-space. If the object begins with a PDF delimiter, then this option is ignored and no white-space is written.

Returns:

the number of bytes written by this method.

Throws:

java.io.IOException
