Class ByteBuffer
- Namespace

Acts like a StringBuilder but works with byte arrays. floating point is converted to a format suitable to the PDF. @author Paulo Soares (psoares@consiste.pt)

ByteBuffer
- Implements
- Inherited Members
Constructors
ByteBuffer()
Creates new ByteBuffer with capacity 128
public ByteBuffer()ByteBuffer(int)
Creates a byte buffer with a certain capacity.
public ByteBuffer(int size)Parameters
sizeintthe initial capacity
Fields
Buf
The buffer where the bytes are stored.
protected byte[] BufField Value
- byte[]
Count
The count of bytes in the buffer.
protected int CountField Value
HighPrecision
If true always output floating point numbers with 6 decimal digits. If false uses the faster, although less precise, representation.
public static bool HighPrecisionField Value
ZERO
public const byte ZERO = 48Field Value
Properties
Buffer
Sets the cache size. This can only be used to increment the size. If the size that is passed through is smaller than the current size, nothing happens.
public byte[] Buffer { get; }Property Value
- byte[]
CanRead
public override bool CanRead { get; }Property Value
CanSeek
public override bool CanSeek { get; }Property Value
CanWrite
public override bool CanWrite { get; }Property Value
Length
public override long Length { get; }Property Value
Position
public override long Position { get; set; }Property Value
Size
Returns the current size of the buffer.
public int Size { get; set; }Property Value
- int
the value of the count field, which is the number of valid bytes in this byte buffer.
Methods
Append(byte)
public ByteBuffer Append(byte b)Parameters

public ByteBuffer Append(string str)Parameters
strstringthe string to be appended
Returns
- ByteBuffer
a reference to this ByteBuffer object
Append(ByteBuffer)
Appends another ByteBuffer to this buffer.
public ByteBuffer Append(ByteBuffer buf)Parameters
bufByteBufferthe ByteBuffer to be appended
Returns

Flush()
public override void Flush()FormatDouble(double)
Outputs a double into a format suitable for the PDF.
public static string FormatDouble(double d)Parameters
ddoublea double
Returns
- string
the string representation of the double
FormatDouble(double, ByteBuffer)
Outputs a double into a format suitable for the PDF. buf is null . If buf is not null , then the double is appended directly to the buffer and this methods returns null .
public static string FormatDouble(double d, ByteBuffer buf)Parameters

ToByteArray()
Creates a newly allocated byte array. Its size is the current size of this output stream and the valid contents of the buffer have been copied into it.
public byte[] ToByteArray()Returns
- byte[]
the current contents of this output stream, as a byte array.
ToString()
Converts the buffer's contents into a string, translating bytes into characters according to the platform's default character encoding.
public override string ToString()Returns
- string
string translated from the buffer's contents.
Write(byte[], int, int)

WriteByte(byte)
public override void WriteByte(byte value)Parameters
valuebyte
WriteTo(Stream)
Writes the complete contents of this byte buffer output to the specified output stream argument, as if by calling the output stream's write method using out.Write(buf, 0, count) . @exception IOException if an I/O error occurs.
public void WriteTo(Stream str)Parameters
strStreamthe output stream to which to write the data.
