SchemeString

public SchemeString()

SchemeString

public SchemeString(java.lang.String s)

SchemeString

public SchemeString(char[] data)

Method Detail

asString

public java.lang.String asString()

length

public int length()

charAt

public char charAt(int index)

valueEqual

public boolean valueEqual(Value v)

Description copied from class: Value

Compares this value to another for semantic equality. Used to implement Scheme's 'equal?'. Subclasses must test for pointer equality as well as semantic equality, so that infinite loops on recursive structures are less likely.

Overrides:

valueEqual in class Value

Parameters:

v - the other Value

valueHashCode

public int valueHashCode()

Description copied from class: Value

a hashCode function consistent with valueEqual

Overrides:

valueHashCode in class Value

Returns:

hash code

appendTo

public void appendTo(java.lang.StringBuffer buf)

copy

public SchemeString copy()

substring

public SchemeString substring(int from,
                              int to)

set

public void set(int k,
                char c)

set

public void set(java.lang.String s)

set

public void set(char[] ca)

readFromReader

public int readFromReader(java.io.Reader r,
                          int off,
                          int len)
                   throws java.io.IOException

Throws:

java.io.IOException

writeToWriter

public void writeToWriter(java.io.Writer w,
                          int off,
                          int len)
                   throws java.io.IOException

Throws:

java.io.IOException

display

public void display(ValueWriter w)
             throws java.io.IOException

Specified by:

display in class Value

Throws:

java.io.IOException

write

public void write(ValueWriter w)
           throws java.io.IOException

Overrides:

write in class Value

Throws:

java.io.IOException

toString

public java.lang.String toString()

Overrides:

toString in class Value

serialize

public void serialize(Serializer s)
               throws java.io.IOException

Description copied from class: Expression

All Expressions must implement a default (no-argument) constructor. Those that wish to be serialized to a heap must implement both this and the deserialize method. The Expression may use any method of the Serializer, which implements java.io.DataOutput to write its state.

Overrides:

serialize in class Expression

Parameters:

s - the Serializer

Throws:

java.io.IOException

deserialize

public void deserialize(Deserializer s)
                 throws java.io.IOException

Description copied from class: Expression

All Expressions must implement a default (no-argument) constructor. Those that wish to b serialized to a heap must implement both this and the serialize method. The Expression may use any method of the DataInput stream and the Deserializer serialization context to read its state.

Overrides:

deserialize in class Expression

Parameters:

s - the Deserializer

Throws:

java.io.IOException
