addCmd

private void addCmd(java.lang.String src,
                    int[] linecol,
                    int from,
                    int to,
                    OutTextPreparer.Cmd cmd)

Common addCmd with given Cmd instance (may be derived). Usable for all ...

Parameters:

src - the pattern or specific String

from - position of text before this cmd from pattern, or from specific String

to - end text after from.

cmd - the intrinsic OutTextPreparer.Cmd to add. Can be null, then not added.

addCmdSimpleVar

private void addCmdSimpleVar(java.lang.String src,
                             int[] linecol,
                             int from,

                             java.lang.String sName)

Called if a simple <&name> is detected. It is searched firstly in idxConstData, then in OutTextPreparer.nameVariables and at least in the execClass via Datapath access. If not found then is output on runtime. It adds the plain text if necessary and the data access calling Cmd#Cmd(ECmd, int, DataAccess, Object, String) to the list of commands.

Parameters:

src - The text before to output the plain text before

from - range in src

to - to > from, then output the plain text

eCmd - The OutTextPreparer.ECmd for the Cmd

sName - name of the argument or variable or field.

execClass - to search in a data field.

private void addCmdValueAccess(java.lang.String src,
                               int[] linecol,
                               int from,
                               int to,

                               java.lang.Class<?> execClass,
                               java.util.Map<java.lang.String,java.lang.Object> idxConstData)

Called if a simple <&name> is detected. It is searched firstly in idxConstData, then in OutTextPreparer.nameVariables and at least in the execClass via Datapath access. If not found then is output on runtime. It adds the plain text if necessary and the data access as Cmd#Cmd(ECmd, int, DataAccess, Object, String) to the list of commands.

Parameters:

src - The text before to output the plain text before

from - range in src

to - to > from, then output the plain text

eCmd - The OutTextPreparer.ECmd for the Cmd

sName - name of the argument or variable or field.

execClass - to search in a data field.

addCmd

private OutTextPreparer.Cmd addCmd(java.lang.String src,
                                   int[] linecol,
                                   int from,
                                   int to,
                                   OutTextPreparer.ECmd ecmd,
                                   java.lang.String sDatapath)

Explore the sDatapath and adds the proper Cmd

Parameters:

src - The pattern to get text contents

from - start position for text content

to - end position for text content, if <= from then no text content is stored (both = 0)

ecmd - The cmd kind

sDatapath - null or a textual data path. It will be split to CalculatorExpr.Operand.ixValue and CalculatorExpr.Operand.dataAccess

reflData - class to main data, usable for static operations, also otxScript for call

idxConstData - container of constant data for compile (parse) time

idxScript - can contain some other OutTextPreparer instances for call.

Returns:

the created Cmd for further parameters.
