public class CCodeData
extends java.lang.Object

This is a helper class to return a peace of c-code with associated type information.

cCode

java.lang.String cCode

The generated code snippet for this expression. This information is not important for further using, only as return string in gen_-routines. Therefore it may be deleted using removeCode();

sTempRef

java.lang.String sTempRef

If true, than the cCode represents a setting of a temporary reference. The reference may be used as reference. It is the last used temporary reference. The result code should be consist of the setting of the temporary reference, with following comma separator of expressions. This strategy is used to disentangle the nesting of method calls in paramter for concatenated calls in Java.

returnMode

private final char returnMode

If true, than the cCode represents a method call, which returned the same reference as used for call, it means the method returns this. This information can be used for concatenation, the reference needn't be taken from the return value.

modeAccess

char modeAccess

The access mode may be changed in comparison with identInfos, if a array element is accessed in this code snippet. This information should be used for evaluating the kind of code snippet.

identInfo

final FieldData identInfo

This is the identInfo of the basicly used variable or value type ClassData.classTypeInfo. Therefore the information about the type of the code snipped maybe alternating,

• at ex. var is an array variable with its identinfo here, but the code snipped contains var[2], therefore the LocalIdents.IdentInfos#dimensionArrayOrFixSize doesnot match to the codesnipped. See dimensionArrayOrFixSize of this class.
• at ex. { 1, 2, 3} is a result of a <constArray> in Java2C.zbnf, but its identInfo here is of the basicly type of the elements.

dimensionArrayOrFixSize

final int dimensionArrayOrFixSize

0 if the value in the code snipped is scalar, 1.. if it is an array. The dimensionArrayOrFixSize may be changed in comparison with identInfos, if a array element is accessed in this code snippet. This information should be used for evaluating the kind of code snippet.

CCodeData

CCodeData(java.lang.String cCode,
          FieldData identInfo)

Initializes the detail information modeAccess and dimensionArrayOrFixSize with the same values as identInfo.

Parameters:

cCode - code snipped

identInfo - the type and access infos to the code snipped.

CCodeData

CCodeData(java.lang.String cCode,
          FieldData identInfo,
          char modeAccess)

Initializes the detail information modeAccess and dimensionArrayOrFixSize with the same values as identInfo.

Parameters:

cCode - code snipped

identInfo - the type and access infos to the code snipped.

CCodeData

CCodeData(java.lang.String cCode,
          FieldData identInfo,
          char modeAccess,
          char returnMode)

Initializes the detail information modeAccess and dimensionArrayOrFixSize with the same values as identInfo.

Parameters:

cCode - code snipped

identInfo - the type and access infos to the code snipped.

CCodeData

CCodeData(java.lang.String cCode,
          FieldData identInfo,
          char modeAccess,
          int dimensionArray)

Initializes the detail information modeAccess and dimensionArrayOrFixSize in a special kind.

Parameters:

cCode - code snipped

identInfo - the type and access infos to the code snipped.

modeAccess -

dimensionArrayOrFixSize -

CCodeData

CCodeData(java.lang.String cCode,
          FieldData identInfo,
          char modeAccess,
          int dimensionArray,
          char returnMode)

Initializes the detail information modeAccess and dimensionArrayOrFixSize in a special kind.

Parameters:

identInfo - the type and access infos to the code snipped.

modeAccess -

dimensionArrayOrFixSize -

isReturnThis

boolean isReturnThis()

isReturnNew

boolean isReturnNew()

getReturnMode

char getReturnMode()

xxxtestAndCast

private java.lang.String xxxtestAndCast(FieldData dstIdentInfo,
                                        char intension)

Tests and generates a cast if a cast to the destination form is necessary.
If it is a static array, a { CONST_ObjectJc(...), fixArraySize, 0, cCode } is generated to initialize a static array.
Otherwise ClassData#testAndcast(ClassData, String, char) is called for the given FieldData.typeClazz from parameter dstIdentInfo

Parameters:

dstIdentInfo - The type of necessity appearance of the code snipped, enclosing the representation of the type.

intension - see ClassData#testAndcast(ClassData, String, char).

Returns:

The original cCode or the casted form.

getTypeName

public java.lang.String getTypeName()

Returns the String representation of the type of the code snipped, detected from the identInfo and its FieldData.typeClazz.

getClassLevelIdents

public LocalIdents getClassLevelIdents()

Returns all class level idents, if the code snipped is a reference of a class type. Especially it able to use, if the code snipped is a reference to a method or field of another class.

getTypeHeaderfilename

public java.lang.String getTypeHeaderfilename()

Returns the name of the Headerfile, which defines the class, if the code snipped is a reference of a class type. Especially it able to use, if the code snipped is a reference to a method or field of another class.

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
