Class Compiler

Represents a compiler that can turn source schema into particular target script/schema, i.e. into database creation script for particular technology (i.e. Oracle, MySQL, PostgreSQL, etc..) or some other code/script (i.e. RecordModel classes, JavaScript classes)

Constructors

Compiler(Schema)

Declaration
protected Compiler(Schema schema)
Parameters
Type Name Description
Schema schema

Fields

m_CompileErrors

Declaration
protected List<SchemaCompilationException> m_CompileErrors
Field Value
Type Description
System.Collections.Generic.List<SchemaCompilationException>

SCRIPT_COMMENT_ATTR

Specifies the comment that will be output for decorated entity in the script

Declaration
public const string SCRIPT_COMMENT_ATTR = "script-comment"
Field Value
Type Description
System.String

SCRIPT_INCLUDE_SECTION

Specifies the name of the file to be included in the output verbatim, i.e.: script-include="mytypes.txt"{}

Declaration
public const string SCRIPT_INCLUDE_SECTION = "script-include"
Field Value
Type Description
System.String

SCRIPT_OUTPUT_NAME_ATTR

Properties

CompileErrors

Returns exception errors that were generated during compilation. This property returns "planned" errors that were caused by input, whereas CompileException returns exception that indicates some more drastic abnormality that broke the compilation

Declaration
public IEnumerable<SchemaCompilationException> CompileErrors { get; }
Property Value
Type Description
System.Collections.Generic.IEnumerable<SchemaCompilationException>

CompileException

Returns exception that surfaced during compilation, or null if source has not compiled yet or no exception happened. This exception is different form CompileErrors because it indicates some un=planned condition that broke the compilation process

Declaration
public Exception CompileException { get; }
Property Value
Type Description
System.Exception

HasCompiled

Returns true to indicate that compiler has already processed the source schema

Declaration
public bool HasCompiled { get; }
Property Value
Type Description
System.Boolean

HasErrors

Returns true when this instance did not compile properly

Declaration
public bool HasErrors { get; }
Property Value
Type Description
System.Boolean

Name

Returns the name of the technology that this compiler targets. i.e. "ORACLE", "RecordModel"

Declaration
public abstract string Name { get; }
Property Value
Type Description
System.String

NameCaseSensitivity

Determines whether output script is case sensitive

Declaration
[Config("$name-case-sensitivity|$case-sensitivity")]
public virtual NameCaseSensitivity NameCaseSensitivity { get; set; }
Property Value
Type Description
NameCaseSensitivity

NameComparison

Returns string comparison options for names that depend on target case sensitivity

Declaration
public StringComparison NameComparison { get; }
Property Value
Type Description
System.StringComparison

OutputPath

Determines where compiled output is placed

Declaration
[Config("$out-path")]
public string OutputPath { get; set; }
Property Value
Type Description
System.String

OutputPrefix

Determines the prefix for output names

Declaration
[Config("$out-name-prefix")]
public string OutputPrefix { get; set; }
Property Value
Type Description
System.String

Schema

Returns source schema

Declaration
public Schema Schema { get; }
Property Value
Type Description
Schema

Target

Returns type of target that this instance produces output for

Declaration
public abstract TargetType Target { get; }
Property Value
Type Description
TargetType

Methods

BuildNodeOutput(IConfigSectionNode, Compiler.Outputs)

Compile()

Declaration
public void Compile()

Configure(IConfigSectionNode)

Declaration
public void Configure(IConfigSectionNode node)
Parameters
Type Name Description

DoCompile()

Performs a compilation - this is a root override-able method where compilation starts

Declaration
protected virtual void DoCompile()

EnsureNotCompiled()

Declaration
protected void EnsureNotCompiled()

EscapeFileName(String)

Replaces incompatible characters for file names with "_"

Declaration
public string EscapeFileName(string fn)

GetOutputFileSuffix(String)

Override to provide meaningful extension for particular technology, i.e. SQL

Declaration
public virtual string GetOutputFileSuffix(string outputName)
Parameters
Type Name Description
System.String outputName
Returns
Type Description
System.String

IncludeScriptFile(IConfigSectionNode, Compiler.Outputs)

Performs a script file include

Declaration
