Cyclomatic:The measure of the complexity of a function's decision structure. The cyclomatic complexity is also the number of basis, or independent, paths through a module. Sometimes also called the "McCabe Complexity" after its originator.
For a precise definition see:
NIST Special Publication 500-235 Structured Testing:
A Testing Methodology Using the Cyclomatic Complexity Metric
Declarations: total number of declarations
Essential Complexity: cyclomatic complexity after structured programming constructs have been removed.
Lines: total lines (in a function or file or project)
Lines Blank: total lines without any code/comment
Lines Code: total lines that have any code on them
Lines Comment: total lines that have comments on them
Lines Declarative: total lines that have declarative code on them
Lines Executable: total lines that have executable code on them
Modified: cyclomatic except each case statement is not counted;the entire switch counts as 1
Nesting: maximum nesting level of control constucts (if, while,etc.)
Path Count: Number of unique paths through a body of code (not counting gotos or abnormal exits.
Ratio Comment/Code: comment lines / code lines
Strict: Cyclomatic complexity except each short-circuit operator adds 1 to the complexity.
Strict Modified Essential: essential complexity except short-circuit operators add to complexity and structured case branches do not add to complexity.
Statements executable: total statements in executable code
Statements declarative: total statements in declarative code
Note, code+comment+blank != lines, as some lines might have both code and comment
Units: Number of program units or functions.
