Detailed Description

A MemoryLimitsAwareHandler handles memory allocation and prevents decompressed pdf streams from occupation of more space than allowed.

Constructor & Destructor Documentation

MemoryLimitsAwareHandler() [1/2]

iText.Kernel.Pdf.MemoryLimitsAwareHandler.MemoryLimitsAwareHandler ( )

inline

Creates a MemoryLimitsAwareHandler which will be used to handle decompression of pdf streams. The max allowed memory limits will be generated by default.

MemoryLimitsAwareHandler() [2/2]

iText.Kernel.Pdf.MemoryLimitsAwareHandler.MemoryLimitsAwareHandler ( long  documentSize )

inline

Creates a MemoryLimitsAwareHandler which will be used to handle decompression of pdf streams. The max allowed memory limits will be generated by default, based on the size of the document.

Parameters

documentSize

the size of the document, which is going to be handled by iText.

Member Function Documentation

GetMaxSizeOfDecompressedPdfStreamsSum()

virtual long iText.Kernel.Pdf.MemoryLimitsAwareHandler.GetMaxSizeOfDecompressedPdfStreamsSum ( )

inlinevirtual

Gets the maximum allowed size which can be occupied by all decompressed pdf streams.

Returns

the maximum allowed size value which streams may occupy

GetMaxSizeOfSingleDecompressedPdfStream()

virtual int iText.Kernel.Pdf.MemoryLimitsAwareHandler.GetMaxSizeOfSingleDecompressedPdfStream ( )

inlinevirtual

Gets the maximum allowed size which can be occupied by a single decompressed pdf stream.

Returns

the maximum allowed size which can be occupied by a single decompressed pdf stream.

SetMaxSizeOfDecompressedPdfStreamsSum()

virtual iText.Kernel.Pdf.MemoryLimitsAwareHandler iText.Kernel.Pdf.MemoryLimitsAwareHandler.SetMaxSizeOfDecompressedPdfStreamsSum ( long  maxSizeOfDecompressedPdfStreamsSum )

inlinevirtual

Sets the maximum allowed size which can be occupied by all decompressed pdf streams.

Sets the maximum allowed size which can be occupied by all decompressed pdf streams. This value can be limited by the maximum expected PDF file size when it's completely decompressed. Setting this value correlates with the maximum processing time spent on document reading iText will throw an exception if during decompression pdf streams with two or more filters of identical type occupy more memory than allowed.

Parameters

maxSizeOfDecompressedPdfStreamsSum

he maximum allowed size which can be occupied by all decompressed pdf streams.

Returns

this MemoryLimitsAwareHandler instance.

SetMaxSizeOfSingleDecompressedPdfStream()

virtual iText.Kernel.Pdf.MemoryLimitsAwareHandler iText.Kernel.Pdf.MemoryLimitsAwareHandler.SetMaxSizeOfSingleDecompressedPdfStream ( int  maxSizeOfSingleDecompressedPdfStream )

inlinevirtual

Sets the maximum allowed size which can be occupied by a single decompressed pdf stream.

Sets the maximum allowed size which can be occupied by a single decompressed pdf stream. This value correlates with maximum heap size. This value should not exceed limit of the heap size. iText will throw an exception if during decompression a pdf stream with two or more filters of identical type occupies more memory than allowed.

Parameters

maxSizeOfSingleDecompressedPdfStream

the maximum allowed size which can be occupied by a single decompressed pdf stream.

Returns

this MemoryLimitsAwareHandler instance.
